Huh, a few of the examples/prose about RSD, pingback, and twitter tags follow the same heading order, and mention the same details with the same links.

Like, it's really no big deal I guess. You were always going to find out this info from sources compiled by other people. But at least don't do the "I'll change some words and call it mine" high school essay plagiarism technique. There was clearly real research done here as well, it's not like it would've been that much harder to write it yourself.

    article:
    > They functioned somewhat similarly to how WebMentions do. Unfortunately, pingbacks rather quickly became an avenue for spam and SEO-gaming, so fell out of fashion. Vulnerabilities allowing sites to be tied up in DDoS attacks also became widely exploited.
